FLUSH-TANK VALVE.

SJPECIFICATIQN forming part of Letters Patent NO. 681,302, dated August27, 1901. Application filed December 31, 1900. Serial No. 41,581. (Nomodel.)

To all whom it may concern.-

Be it known that I, JOHN DENTON, a citizen of the United States,residing in Paterson, countyjof Passaic, and State of New Jersey, haveinvented new and useful Improvements in Flush-Tank Valves; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to characters of reference marked thereon,which forma part of this specification.

This invention relates to flushing apparatus for water-closets, and ithas reference particularly to the construction of the sup ply-valve ofsuch an apparatus.

' The invention consists in the improved supply-valve for a flushingapparatus for waterclosets and in the combination and arrangements ofits various parts, substantially as will be hereinafter pointed out, andfinally embodied in the clauses of the claim.

Referring to the accompanying drawings, wherein the invention is fullyillustrated, Figure 1 is a view of a flushing apparatus provided with myimproved supply-valve. Fig. 2 is an enlarged vertical sectional view ofthe supply-valve. Fig. 3 is a vertical sectional View of a modified formof the supplyvalve, and Fig. 4 illustrates a detail of the valve.

In the drawings, a designates a tank of any suitable construction, and band 0 denote the supply and discharge pipes. In the discharge-pipe islocated a valve-casing d, having a valve 6, which controls the flow fromthe tank through said pipe and which is adapted to be actuated by alever f, having the usual chain g and connected with the valve by avalve-stem h.

t designates the valve-casing for the supply-pipe. This casing comprisesa chamber portion j and a tubular portion is, preferably integrallyformed and having a communicating port Z. To one end of the tubularportion 70 is adapted to be attached,by a suitable coupling m,thesupply-pipe b. The chamber portion j is provided with alined andthreaded openings n 0. One of these is fitted with a threaded plug 19,while the other, 0, receives the threaded end of a tubular thimble g,which penetrates the bottom wall of the tank and is provided with anenlargement r at its upper end,which when the thimble is screwed tightlyinto place in the valve-casing coacts with the casing in binding saidwall between them, and thus producing a tight joint. A washer 8 may beinterposed between the enlargement and said wall. A washert may likewisebe interposed between the, casing and said wall, the former being,asbest shown in Fig. 2, provided with an annular groove a, formed aboutthe threaded opening 0 and adapted to receive said washer. Theenlargement r is provided with a dischargeopening 1), and its upper endis covered by a cap to, which is preferably screwed into place andcarries an arm 58, upon which is fulcrumed a short lever y, adapted toreceive the end of a stem z for a float 2.

The lower end of the thimble q forms a port of communication between thevalvecasing and the body portion of said thimble, and it is adapted tobe controlled by a plug 3, which seats against the end of the thimble,-being carried bya valve-stem 4, which penetrates the thimble andprotrudes through its cap, its head 5 having an opening 6, through whichthe lever extends. In order to guide the-valve-stem and, thus insure theproper seating of the valve, the former may be extended, as seen in Fig.2, so as to project into the bore 7 of an integral nipple 8, formed onthe plug p. The extended portion,- for a reason hereinafter explained,is shown in the drawings as made separable from the body portion of thestem; but it is to be understood that it may be made integral therewith.

In order to secure the valve-casing against turning on the thimble, itmay be secured by screws or other devices 9.

In the modification of my invention shown in Fig. 3 a somewhat cheaperconstruction is produced, an ordinary T 10 being used for thevalve-casing. This figure also illustrates that solder may be employedto insure a tight joint on the inside of the tank around the thimble, asat 10.

The plug or valve 3 is preferably secured on the valve-stem 4 by an adjListing-screw 11, which is tapped into the end of the valvestem, thisend taking against a washer 12, between which and another washer 13 onthe valve-stem the valve is compressed. The end of the valve-stem isreduced, thus forming a shoulder 14, against which the washer 13 abuts.This construction permits the adj ustment of the shape of the plug orvalve, it thus being capable of being altered to fit the particularvalve-seat to which it is applied, it being remarked that said valve ismade of elastic rubber. The separable plug 19 permits access to theinterior of the valve-casing 71, either for cleaning the same oradjusting or replacing the valve 3. In order to perfectly insure theseating of the valve 3, as when pressure in pipe I) is high, a spiralspring may be interposed between the bottom of the valve and the plugp,said spring receiving at its upper end the end of the valve-stem.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a flushing apparatus, the combination of a tank, a supply-pipe, ahollow thimble penetrating one of the Walls of said tank and having anapertured enlargement adapted to take against one side of said wall, avalvecasing screwed onto the other end of said thin1- ble and adapted toengage the other side of said wall, said pipe being connected with saidvalve-casing, a plug removably secured in said valve-casing in alinementwith the thimble, a valve-stein penetrating said thimble,

and a valve controlling the communication between the thimble and thevalve-casing and disposed on the end of said valve-stem.which isinclosed by the casing, substantially as described. v

2. In a flushing apparatus, the combination of a tank, a supply-pipe, ahollow thimble penetrating one of the walls of said tank and having anapertured enlargement adapted to take against one side of said wall, avalvecasing screwed on the other end of said thimble and adapted toengage the other side of said wall, said pipe being connected with saidvalve-casing, a plug removably secured in said valve-casin g inalinement with the thimble, a valve-stem penetrating said thimble, anelastic valve controlling communication between the thimble and thevalve-casing and disposed on the end of said valve-stem which isinclosed by the casing, said valve-stem having an abutment against whichthe valve takes, and a headed screw tapped into said end of thevalve-stein and adapted for adjusting the valve, said screw being guidedin the plug, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this17th day of December, 1900.

JOHN DENTON.
